Modulation Of Cholinergic Signaling In Embryonic Zebrafish: Anatomical And Behavioral Consequences, Evdokia Menelaou Jan 2010

Modulation Of Cholinergic Signaling In Embryonic Zebrafish: Anatomical And Behavioral Consequences, Evdokia Menelaou

LSU Doctoral Dissertations

Smoking during pregnancy remains a major health concern in the United States. Nicotine is one of the main ingredients of cigarettes and a neurotoxicant which has been purported to affect many aspects of nervous system development causing long-term abnormalities in the offspring. We took advantage of the zebrafish model to investigate the effects of nicotine in nervous system anatomy and function. It was previously reported that embryonic nicotine exposure causes pathfinding errors in secondary motoneuron (SMN) axons through the activation of nicotine acetylcholine receptors (nAChRs). However, the nicotine-induced effects on SMN pathfinding coincided with muscle degeneration. We hypothesized that nicotine …

The Blame Is In The Frame: Inter-Reality Comparisons Of Crime Reports And Local News Crime Coverage On The Internet, Dana Marie Tumblin Jan 2010

The Blame Is In The Frame: Inter-Reality Comparisons Of Crime Reports And Local News Crime Coverage On The Internet, Dana Marie Tumblin

LSU Master's Theses

Research of crime news suggests that Blacks are over represented as criminals when compared to crime reports; study of race and crime judgments reveals that viewers with heavy amounts of television news viewing associate Blacks with crime more often than viewers who watch lower amounts of television news. Further complicating the perception of Blacks is their lack of diversified coverage in the news. Most coverage of Blacks frames them as liabilities to their communities, while offering few positive depictions to counter the Black criminality frame. The Internet may aid in exacerbating stereotypes of Blacks by allowing users to selectively expose …

Communicating Conservation: Public Relations Practitioners' Communication Efforts To Inform The Public Of The Detriments Of Coastal Erosion And Wetlands Loss, Stephanie Ellene Shaddock Jan 2010

Communicating Conservation: Public Relations Practitioners' Communication Efforts To Inform The Public Of The Detriments Of Coastal Erosion And Wetlands Loss, Stephanie Ellene Shaddock

LSU Master's Theses

Coastal erosion is a serious problem that directly affects Louisiana and indirectly affects the entire United States. Between 1990 and 2000, Louisiana lost 24 square miles of land per year, which equals an approximate football field lost every 38 minutes (Barras, Bourgeois, & Handley, 1994). Hurricanes Katrina and Rita in 2005 accelerated this land loss by transforming 217 square miles of marsh into open water (United States Geological Survey, 2006). As a leader in seafood, oil, and gas production, and shipping state, Louisiana and the nation have much at stake with continued land loss. To inform Louisiana’s citizens and a …

Reproduction In Female Diploid And Triploid Eastern Oysters (Crassostrea Virginica): Comparison Of Gonadal Changes Correlated With Prostaglandin E2, Esther Faith Young

LSU Master's Theses

The sale of eastern oysters (Crassostrea virginica) is a multi-million dollar industry in the United States. Triploid production of oysters helps to alleviate the decline in sales during summer months that normally results from the loss of flavor and texture when diploid oysters are spawning. Research to improve the ease of triploid production is critical for the expansion of oyster hatcheries producing triploids. The goals of this research were to determine the period of time when triploid oysters are most fertile and to determine if prostaglandin E2 (PGE) plays a role in oocyte maturation of C. virginica. The results of …

Is A Student's Conceptual Knowledge Affected By Their Vocabulary Instruction?, Daniel C. Cox Jan 2010

Is A Student's Conceptual Knowledge Affected By Their Vocabulary Instruction?, Daniel C. Cox

LSU Master's Theses

The following paper explores the possible relationship between the manner in which a student is taught vocabulary in a high school physics classroom and the ability of those students to correctly answer physics conceptual questions. Two high school physics classes taught by the same teacher (eight or nine students in one and seventeen in the other) received identical instruction throughout multiple units with the exception of vocabulary instruction. Differences were observed in the students’ ability to correctly answer conceptual questions in only one topic, heat. The students did not get better at answering a question concerning a phase change or …

"Unspottyd Lambs Of The Lord": Presbyterianism And The People In Elizabethan London, Katherine E. Sawyer Jan 2010

"Unspottyd Lambs Of The Lord": Presbyterianism And The People In Elizabethan London, Katherine E. Sawyer

LSU Master's Theses

The official English church in the mid-sixteenth century vacillated back and forth between Catholicism and Protestantism, the two rivals of European Christianity. As these changes engendered a broad array of disagreements over issues such as liturgical practices, clerical attire, and church ornamentation, this thesis focuses on the most provocative of these debates-presbyterianism-and its proliferation among the men and women of Elizabethan London. Despite the propagation of presbyterian-style nonconformity in several regions of Elizabeth's realm, London functioned as the epicenter of this challenge to religious orthodoxy. From their location at the economic, religious, and cultural heart of the nation, Elizabethan Londoners …

Modeling And Multiresolution Characterization Of Micro/Nano Surface For Novel Tailored Nanostructures, Rajib Mukherjee Jan 2010

Modeling And Multiresolution Characterization Of Micro/Nano Surface For Novel Tailored Nanostructures, Rajib Mukherjee

LSU Doctoral Dissertations

Nanofabrication is state of the art technology. Various chemical, mechanical, biochemical and semiconductor products have characteristics controlled by the nanostructures of the surface and interphase. Surface microscopic imaging is generally used to capture different surface features. By properly analyzing the surface image, valuable information regarding manufacturing process and product performance can be extracted. While microscopy measurements can offer very accurate qualitative information about surface features, for many applications, it is critical to obtain a quantitative description of the surface morphology. Various statistical features can be used to characterize the surface in quantitative way. Such an analysis can be done by …

Pliny's Defense Of Empire, Thomas Raymond Laehn Jan 2010

Pliny's Defense Of Empire, Thomas Raymond Laehn

LSU Doctoral Dissertations

Despite perennial interest in Pliny the Elder’s Natural History as a record of the prodigious, the quotidian, and the useful in Rome in the first century AD, for over half of a millennium Pliny has been considered little more than an inept compiler of facts and marvels intellectually incapable of formulating a cogent argument supported through the selective marshalling of his materials. It is my contention that Pliny’s encyclopedic text is in fact a first-rate work of political philosophy constituting an apology for Roman imperial expansion grounded in a sophisticated conception of man as the only being capable of passing …

A Survey Of Professional Operatic Entertainment In Little Rock, Arkansas: 1870-1900, Jenna M. Tucker

LSU Doctoral Dissertations

The late nineteenth century was a time of great political, economic, and social change in the state of Arkansas. The population of Little Rock, the state capital, nearly tripled in the last thirty years of the century. As more people settled in Little Rock, the demand for entertainment grew. Poor transportation was an initial obstacle; but as railroads gradually linked Little Rock to larger cities, traveling professional theatrical troupes began to include Little Rock on their itineraries. The purpose of this project is to document the history of professional operatic entertainment in Little Rock, Arkansas, from 1870—when the first professional …

Early American Self-Reflexive Writing: Revising The Tradition, Susie Scifres Kuilan Jan 2010

Early American Self-Reflexive Writing: Revising The Tradition, Susie Scifres Kuilan

LSU Doctoral Dissertations

This study focuses on self- reflexivity in early American texts. This self-reflexivity demonstrates that these early American authors were attempting to define “American fiction” and were participating in a new literary tradition that was developing simultaneously with the development of the new country. After the introduction, Chapter One lays the groundwork for my study by exploring current views of these texts and what led to these views. Chapter Two explores the difficulties facing post-Revolutionary authors and their reactions to these obstacles as reflected in their prefaces and their other writings. I show the way these authors self-consciously respond to the …

Electrodeposited Cu-Based Catalysts For Alcohols From Co Hydrogenation And Electrodeposition Of Cuniw/Cuni Multilayered Alloys, Mayank Gupta Jan 2010

Electrodeposited Cu-Based Catalysts For Alcohols From Co Hydrogenation And Electrodeposition Of Cuniw/Cuni Multilayered Alloys, Mayank Gupta

LSU Doctoral Dissertations

Ethanol and higher alcohols can be used as a fuel or fuel additive in gasoline engines as well as a hydrogen carrier. One of the promising methods to synthesize these alcohols is based on thermochemical conversion of CO and H2 (CO hydrogenation). Conventional catalysts used for the conversion CO and H2 (syngas) to ethanol typically give yields less than 20% with the balance resulting mostly in the formation of the thermodynamically favored products CH4 and CO2. New catalysts with compositions designed to kinetically favor the formation of ethanol and higher alcohols are needed. Electrodeposition of nanowires offers a means to …

Ethnic Composition And The Dynamics Of Civil War: A Subnational Analysis Of India And Pakistan, Caroline Lee Payne Jan 2010

Ethnic Composition And The Dynamics Of Civil War: A Subnational Analysis Of India And Pakistan, Caroline Lee Payne

LSU Doctoral Dissertations

Scholars, policymakers, and the media present a conflicting picture of the relationship between ethnicity and civil conflict. In order to clear up the confusion and better establish this relationship, I argue that it is necessary to: (1) distinguish between different types of ethnic composition; (2) conceptualize and measure ethnic composition as not only a static phenomenon but a dynamic one in which population changes alter group security calculations and therefore their decision making; (3) consider the unique mobilization capacity of ethnic groups; and (4) examine the effect of ethnic composition at the subnational level of analysis. In doing so, this …

Diatom Stratigraphy Defining Ice Sheet Grounding Chronology, Ross Sea, Antarctica, Juan Manuel Chow Jan 2010

Diatom Stratigraphy Defining Ice Sheet Grounding Chronology, Ross Sea, Antarctica, Juan Manuel Chow

LSU Doctoral Dissertations

Evidence of Antarctic ice sheet behavior and paleoenvironment is often approached from proxy records because there is a dearth of direct records from Antarctica itself. The studies presented here seek to augment our knowledge of translations of the West Antarctic Ice Sheet’s (WAIS) marine termination based on direct biostratigraphic evidence. Diatom analyses were conducted from two areas of Ross Sea, Antarctica. In the first study, diatoms were used to constrain the age of diamictons from five seismic units in the Eastern Basin and thus expand our knowledge of WAIS behavior during the Southern Hemisphere Last Glacial Maximum (LGM). All five …

X-Ray Absorption Spectroscopy Applied To Mixed-Metal Iron-Based Fischer-Tropsch Catalysts, Andrew Allen Campos Jan 2010

X-Ray Absorption Spectroscopy Applied To Mixed-Metal Iron-Based Fischer-Tropsch Catalysts, Andrew Allen Campos

LSU Doctoral Dissertations

Synthetic fuels derived from methane, coal or biomass are essential in addressing future transportation fuel demands which are expected to exceed petroleum-derived capacities. The Fischer-Tropsch synthesis (FTS) is the most studied technique for the conversion of coal or biomass-derived syngas into transportation fuels. Fe-based catalysts are typically used for the FTS of biomass and/or coal-derived syngas due to: the relatively low cost of iron, water-gas shift activity, and low methane selectivity at industrial FTS conditions. Fe/Cu/SiO2 Fischer-Tropsch catalysts promoted with Cr, Mn, Mo, W, or Zr were studied in-situ, using Fe K-edge TPR XANES (temperature programmed reduction X-ray absorption near-edge …

Oxidation Of Reduced Sulfur Compounds: A Triple-Oxygen-Isotope Perspective, Issaku E. Kohl Jan 2010

Oxidation Of Reduced Sulfur Compounds: A Triple-Oxygen-Isotope Perspective, Issaku E. Kohl

LSU Doctoral Dissertations

The Earth’s geochemical evolution is recorded in the rocks that compose its lithosphere. Specifically, sulfate minerals have been identified as being repositories of information concerning the past hydrosphere, atmosphere and biosphere. This is due to the non-labile nature of SO42- and its ability to store a record of the oxidative reactions and oxygen sources involved in its formation. Microbial dissimilatory sulfate reduction (MDSR) and sulfide oxidation cause oxygen from H2O and O2 to be trapped to varying degrees in ambient, dissolved SO42-. In order to better interpret the H2O and O2 signals in SO42-, we must deepen our understanding of …

Modeling And Simulation For Shape Memory Polymer Based Self-Healing Syntactic Foam, Wei Xu Jan 2010

Modeling And Simulation For Shape Memory Polymer Based Self-Healing Syntactic Foam, Wei Xu

LSU Doctoral Dissertations

Syntactic foams, renowned for their low density and high mechanical properties, are enjoying continuing growth in various civilian and military sectors. However, like laminated composites, foam cored structures are vulnerable to impact damages and suffering from inabilities in repairing macro-scale cracks. A self-healing mechanism for structural damage is genuinely desired. A recent development in self-healing structural damage is a two-step close then heal (CTH) scheme proposed by Li and Nettles [1] and elucidated by Li and Uppu [2], by mimicking the self-healing process of human skin. This concept has been further demonstrated in Nji and Li’s work [3] that a …

Hepatotoxic Cyanobacterial Blooms In Louisiana's Estuaries: Analysis Of Risk To Blue Crab (Callinectes Sapidus) Following Exposure To Microcystins, Ana Cristina Garcia Jan 2010

Hepatotoxic Cyanobacterial Blooms In Louisiana's Estuaries: Analysis Of Risk To Blue Crab (Callinectes Sapidus) Following Exposure To Microcystins, Ana Cristina Garcia

LSU Master's Theses

The most common toxins detected following freshwater harmful algal blooms are microcystins, a group of hepatotoxins produced by cyanobacteria (e.g., Microcystis and Anabaena spp.). Preference for filter-feeding prey, including bivalves, makes the blue crab, Callinectes sapidus, vulnerable to microcystin contamination and makes the commercially important crab a potential vector of microcystins. I used a combination of field and laboratory studies to determine blue crab vulnerability to microcystin contamination and consequent impacts on crab physiology. Samples collected from a hyper-eutrophic freshwater lake, Lac des Allemands, Louisiana, were analyzed for cyanobacterial abundances and microcystins in surface water and blue crabs using light-microscopy …

Telemaco Signorini: Spokesman Of The Macchiaioli, Christine Elizabeth Morgan Jan 2010

Telemaco Signorini: Spokesman Of The Macchiaioli, Christine Elizabeth Morgan

LSU Master's Theses

Telemaco Signorini was a member of a nineteenth-century Italian group of artists called the Macchiaioli. He was the son of Giovanni Signorini, a painter. The group came together against the Italian academies and drew inspiration from Decamps and the artists of the Barbizon school in France. Their style emphasizes effect and emotion. The Macchiaioli were a short lived group that only lasted from 1855 to 1862. Signorini and the members of the group participated in 1859 in the Risorgimento, the Italian struggle for independence. Based on this experience Signorini created several canvases depicting the Italian countryside, especially at La Spezia. …

Resistant Starch And Sodium Butyrate Reduce Body Fat In Rodents, Kirk Adam Vidrine

LSU Master's Theses

Introduction: Obesity levels in the United States have significantly increased in the last forty years. Lifestyle and pharmacological treatments have been largely ineffective in treating obesity for most people. Both Resistant Starch (RS) and Dietary Sodium Butyrate (SB) are bioactivties which have shown the ability to decrease body fat levels of rodents without increasing physical activity or decreasing energy intake. Glucagon-like peptide 1 (GLP-1) and peptide YY (PYY) are gut hormones that may be involved in increased energy expenditure at a cellular level with dietary RS and SB. Objective: To discern if SB and RS both work through the increase …

Effects Of Emulsion Coatings On The Internal Quality And Shelf Life Of Eggs, Damir Dennis Torrico Jan 2010

Effects Of Emulsion Coatings On The Internal Quality And Shelf Life Of Eggs, Damir Dennis Torrico

LSU Master's Theses

Mineral oil (MO) is currently used for coating eggs to preserve quality. Chitosan possesses inherent antimicrobial and film-forming properties. Chitosan coating (CH) is dried much faster than MO when applied on egg shell. Information on synergistic effects of MO:CH emulsion coatings on egg quality does not exist. We developed MO:CH emulsion coatings, and evaluated their effects on internal quality and shelf-life of eggs during storage. In the first study, MO, CH and three emulsions (MO:CH = 75:25, 50:50, and 25:75) were evaluated during 5 weeks at 25°C. Haugh unit (HU) and yolk index values decreased whereas weight loss increased during …

Prejudice And The New Latino Migration: The Geographic Locus Of Anti-Latino Sentiment, Angela Caraway Jan 2010

Prejudice And The New Latino Migration: The Geographic Locus Of Anti-Latino Sentiment, Angela Caraway

LSU Master's Theses

A large body of literature on the relationship between prejudice and discrimination and the size of minority populations suggests that as a minority population increases so will incidents of prejudice and/or discrimination. This school of thought is led by Hubert Blalock who contends that large minority populations generate prejudice among the majority, who view the minority as a threat to their economic and/or political standing. Minority population size has been tested and widely confirmed as a cause of anti-black prejudice and discrimination. But the corresponding research for Latinos has generally produced inconsistent and largely inconclusive findings. The reason for this …

A Comparison Of Public And Private Positive Peer Reporting In General Education Classrooms, Carolyn Barahona Jan 2010

A Comparison Of Public And Private Positive Peer Reporting In General Education Classrooms, Carolyn Barahona

LSU Master's Theses

Positive peer reporting (PPR) and Tootling have shown to be effective classwide interventions in decreasing maladaptive behavior and increasing positive interactions. In the current study, PPR was implemented as a classwide intervention by using an interdependent group contingency to determine if two variations of student praise reports affect classroom disruptive behavior. PPR uses public praise reports to decrease maladaptive behavior and increase prosocial interactions, while Tootling uses private praise reports on index cards to increase reports of prosocial interactions. This study compared students’ public praise reports to private praise reports of fellow students and evaluated how different praise types affect …
